Green Supply Chain Management Practices and Company Performance: A Meta-analysis approach

Varying conceptualizations of green supply chain management (GSCM) practices can be observed in extant literature and there is evidence of mixed results relating GSCM practices to firm performance. These inconclusive findings have often confused managers which practices would yield desired performance outcomes. Hence, by applying meta-analysis approach in 85 independent effect sizes with a total sample size of 20011 firms, we tested the impact of GSCM practices on firm performance. Findings indicate that the relationship between GSCM practices and firm performance is positive and significant, providing empirical generalization and support to practitioners and scholars. Likewise, the GSCM practices positively and significantly influence environmental, social, operational and economic performance. This relationship is moderated by geographical region, industry type and firm size. Future studies should test how ascendants of GSCM practices affect firm's sustainability performance.
